LETTER-BOX.

SPECIFICATION forming part of Letters Patent No. 301,889, dated July 15, 1884. i

1"@ all whom t may macerie:

Be it known that I, GEORGE C. HENRY, a citizen of the United States, residing at Bun lington, Des Moines county, Iowa, have invented a new and useful Improvement in Letter-Boxes, of which the following isa specilication. p

My invention relates to improvements in letter-boxes; and the object of it is to provide with an alarm the letter-box of Abner S. Cook, Patent No. 298,733, for the purpose of advising'of the arrival of .mail and to prevent abstraction from the box by thieves. This Iaccomplish by theV device illnstratedin the accompanying drawing, which is a vertical section of the letter-box with my alarm attached.

A is a,call-bell, gong, or other suitable alarm, fastened to the inside of the box near the top of it by an elbow-joint to the perpendicular lever-arm O, the upper end of which passes through a perforation in the top T of the box and forms a slight projection when the lid `L is raised.

D is a flexible rod, preferably of steel, clamped or otherwise suitably fastened to the To the projecting` end of D is attached a perpendicular striking-rod, E, provided with a shoulder, I, to engage a catch, F, suitably fastened to the bottom B of the box.

The operation of my invention is as follows: VWhen the lid L is raised the weight of hammer G causes G to proj eet, and when released the closing-spring, by which it is fastened,

the hammer G with force against the alarm A The bottom B of the box, when opened, will, by the catch F and the rod E, pull the spring D downward. As soon as the catch E becomes detached from the shoulder I, as it will when thelboX-bottom is further opened, the spring D will cause the upper end of the rod E to strike violently against the alarm A.

It is evident that I need not confine myself to any particular form of alarm, nor to any particular construction of hammer, rods, lever. spring, or' catch; nor do I confine myself to Aplacing the device shown or its equivalents inside ofthe bor.v It may be placed on' the outside, though the inside is preferable on acj count of weather.

I do not broadly claim an alarm as herein shown and described.

Vhat I claim, and desire to secure by Letters Patent, is i l. In a letter-box Vhaving` lid L and bottom B attached thereto by closing springs, an alarm composed of the bell or gong A, the rod E, provided with hammer G, and pivoted at b, and the lever-arm O, substantially as and for the purpose herein described.

2. In a letter-box, provided with lid L and bottom B,attached thereto by closing-springs, an alarm consisting of the bell or gong A, the spring D, and the striking-rod E, fastened to D,- and provided with shoulder I, to engage the catch F, substantially as and for the purpose herein described.
